so i am thinkin about bolting two tires together on each side of axle. And say i was going down a trail and there was big ruts from four wheeler, and driving across the ruts with just the outer tires supporting the mower do you guys think the axle will bend.

personally i thought i would do this ages ago but two things stopped me

no money for strong enough bolts and since i locked my diff the damage to my lawn and to the driveway would have been too bad...

double tyres shouldn't worry you as the only issue i could think of is the bolts as they would have to be heavy duty, the gearbox should handle the strain mines balanced on one wheel with the other in the air going up a fallen tree and it held up fine, i had two ideas and i might as well blurt the out ATM

one - drill four holes in two tyres and bolt together this was the simple way and cost effective way

two - weld an old drive shaft from an old gearbox to the existing ones, this would be irreversible but if you welded it right AKA 3 or four spot welds, then instead of the gearbox breaking the welds would snap, which would be good as you would still have one tyre to get you home!

dunno i think the bolt idea is a bit risky although my second idea is better if you want a transaxle that wont break although this is more expensive...
